I'm in the market for a Macbook Pro and I went to an Apple Store today to see the differences between a 13" and a 15". Essentially the same 'guts' inside but I did notice how much brighter the 15" screen was in comparison to the 13". Enough so that the employee seemed to think it was strange and pulled another new one and also a refurb unit to compare. In all cases the 15" screen was brighter then the 13" current gen, previous gen, and in comparison to the air. Is this just a fluke or in your experiences, is the current gen's 15" display about 25% brighter then the current gen 13" model? I was all for only buying the 13" but it seemed so dim in comparison that I'll probably go for the 15". We did adjust the brightness settings and all units were running on ac power. I have really good eyesight (no glasses or contacts) so maybe I'm just sensitive to it. In my opinion the 13" in comparison to the 15" looked dim like when you run a laptop straight from battery power instead of being on ac. Thoughts?
